[0002] New energy vehicles are an important part of the development of the new energy industry. New energy vehicles are powered by electricity, replacing fossil fuels, achieving environmental protection and saving chemical energy. With the rapid development of new energy vehicles, fuel vehicles will continue to be replaced and new energy will be fully realized. In new energy vehicles, the motor is an important core power component, which relies on electricity to achieve the movement of the car. Therefore, the performance parameters of the motor are crucial detection contents. The current motor testing equipment has a relatively single detection function and is not very practical.

[0029] After the installation of the motor 2303 to be tested is completed, it is driven by the power module 2302, and a sensor for detecting performance parameters is installed on the motor 2303 to be tested; the motor 2303 to be tested is in the detection area, that is, the slide 23 is limited and fixed in the detection area, and the limit plate 27 is controlled to move by the limit cylinder 26, so that the limit plate 27 is located on the side of the roller 24 to complete the limit fixation of the slide 23; the temperature control cover 12 can be controlled to move by the lifting control electric cylinder 14, so that the temperature control cover 12 covers the outside of the motor 2303 to be tested, and further, low temperature adjustment is performed by the low temperature controller 13.

After the load fixing seat 46 fixes the counterweight plate 18, the buckle seat 1 48 is buckled with the buckle seat 2 49 to fix the load fixing seat 46. When releasing the fixation, the buckle seat 2 49 is controlled to be extended and retracted by the electromagnetic telescopic rod 51, that is, the buckle seat 2 49 is disengaged from the buckle seat 1 48, and the load fixing seat 46 moves under the elastic force of the compression spring 1 47 to separate from the inner side of the counterweight plate 18.
